#include <net_l2.h>

Data Fields
enum net_verdict(*	recv )(struct net_if *iface, struct net_pkt *pkt)
	This function is used by net core to get iface's L2 layer parsing what's relevant to itself.
int(*	send )(struct net_if *iface, struct net_pkt *pkt)
	This function is used by net core to push a packet to lower layer (interface's L2), which in turn might work on the packet relevantly.
int(*	enable )(struct net_if *iface, bool state)
	This function is used to enable/disable traffic over a network interface.
enum net_l2_flags(*	get_flags )(struct net_if *iface)
	Return L2 flags for the network interface.
int(*	alloc )(struct net_if *iface, struct net_pkt *pkt, size_t size, enum net_ip_protocol proto, k_timeout_t timeout)
	Optional function for reserving L2 header space for this technology.

Detailed Description

Network L2 structure.

Used to provide an interface to lower network stack.

Field Documentation

alloc

int(* net_l2::alloc) (struct net_if *iface, struct net_pkt *pkt, size_t size, enum net_ip_protocol proto, k_timeout_t timeout)

Optional function for reserving L2 header space for this technology.

enable

int(* net_l2::enable) (struct net_if *iface, bool state)

This function is used to enable/disable traffic over a network interface.

The function returns <0 if error and >=0 if no error.

get_flags

enum net_l2_flags(* net_l2::get_flags) (struct net_if *iface)

Return L2 flags for the network interface.

recv

enum net_verdict(* net_l2::recv) (struct net_if *iface, struct net_pkt *pkt)

This function is used by net core to get iface's L2 layer parsing what's relevant to itself.

send

int(* net_l2::send) (struct net_if *iface, struct net_pkt *pkt)

This function is used by net core to push a packet to lower layer (interface's L2), which in turn might work on the packet relevantly.

(adding proper header etc...) Returns a negative error code, or the number of bytes sent otherwise.
